CUSTOMER CONCERN The transmission will not shift out of Park, the dash displays an Automatic Shift Fault warning, and DTCs U019E and U101F reset after clearing. CAUSE The Transmission Range Control Module did not communicate with multiple scan tools while all other modules remained accessible. Circuit checks supported a failed TRCM, and the exact-vehicle confirmed repair replaced the module. CORRECTION Remove and replace the failed Transmission Range Control Module, adjust th

CUSTOMER CONCERN Check-engine warning is on with DTC P2602, and replacing the inverter water pump did not stop the code from returning. CAUSE P2602 applied to the transaxle oil-circulation pump rather than the inverter coolant pump. Power, ground and control-circuit testing identified the transmission oil-pump assembly as the failed component. CORRECTION Remove and replace the transmission oil-pump assembly, clear DTC P2602, and verify transaxle oil-pump operation.

CUSTOMER CONCERN Customer states the vehicle will not start, will not shift out of Park and cannot be switched off normally after the discharged 12-volt battery was replaced. DTC C2309 is stored. CAUSE Confirmed failed IGCT relay interrupted B+ power through the IGCT No. 2 and No. 3 fuse circuits to the transmission control ECU. The Blue wire at terminal 16 of connector A should receive battery voltage with the power switch on; C2309 sets when ECU B+ remains at 3 volts or les

CUSTOMER CONCERN Customer states the transmission does not shift correctly. DTC P1775 is stored for the electric oil-pump status circuit along with C-CAN communication DTC U1007. CAUSE Confirmed open circuits in wires 3 and 6 adjacent to electric oil-pump control unit connector E64-B. CORRECTION Repair the open circuits at wires 3 and 6 near electric oil-pump control unit connector E64-B.
